Hi,
We have a 8 year old 4 channel 2 Gsamples/sec 500MHz HP Infinium that has suffered overvoltage in 2 of the 4 channels. Wondering if anyone has attempted repair at component level themselves for this type of occurence? Agilent will charge at least $3000 per channel for repair. Since 2 channels are buggered and 1 is showing poor cal, it is time to decide to turf it and get a Tektronix or attempt repair. Would like to here if anyone has done similar.
